In the extraction by flushing a fluid flows through the inside of a closed component to detach the particles of the wetted inner surface and to drag them out. 

The method is the practical simulation of a flow-through process. It is use for parts like:

  • spuelenPipes
  • Filters
  • Heat exchangers
  • Pumps
  • Valves
  • Transmissions etc..

Here are the particles collected on a membrane and analyzed.

The characteristic parameters such as flow rate, amount of fluid, flushing pressure and flushing time are determinate by the decay curve
